KAFFIR LIME MOUTHWASH : HERBAL INNOVATION FOR ORAL HYGIENE AND HALITOSIS PREVENTION

Abstract

Halitosis is an oral health problem that can reduce quality of life and self-confidence. The use of chemical-based mouthwash often causes side effects; therefore, a safe and effective natural alternative is needed. This study aimed to evaluate the physical quality and effectiveness of mouthwash formulated from kaffir lime (Citrus hystrix DC.) juice in preventing halitosis among students of the Dental Health Department. Three formulas (F1, F2, F3) were tested for organoleptic properties, homogeneity, viscosity, pH, hedonic preference, and organoleptic assessment of halitosis reduction. The results showed that formula F3 had a slightly cloudy white color, a mild fresh aroma, the most preferred taste, and high stability without phase separation during storage. All formulas exhibited an ideal viscosity of approximately 1000 mPas, with F3 showing the most stable pH (5.0–5.1), close to the physiological pH of the oral cavity. Hedonic testing confirmed the highest user acceptance for F3. In conclusion, F3 was the best formula based on physical quality, sensory acceptance, and effectiveness in reducing halitosis. Kaffir lime mouthwash has the potential to serve as a safe and effective herbal alternative for oral health care.
